The Sognefjord Spans are the second, third, and fourth longest spans in the world situated east of Hermansverk, Norway and are part of different powerlines. As Sognefjord Span is a deep valley the pylons of these spans are not taller than ordinary pylons. In order to avoid any too close approaches or contacts between the conductors, each is mounted on a separate pylon at the end of the span, which is built as a steel framework tower.
This span is part of the powerline between Hermansverk 61°10′49″N 6°51′53″E / 61.18028°N 6.86472°E and Vikøyri 61°04′50″N 6°35′13″E / 61.08056°N 6.58694°E and was built in the 1950s.
